Ruby-on-Rails application which serves top performing advertising
banners for a given campaign.
When a request hits the URL for a particular campaign
(e.g. http://localhost:3000/campaigns/:campaign_id), it will serve
one of the top performing banners for that campaign.
The application picks a banner based on its click-to-conversion performance & click count for the specific campaign.
- Banners generating most revenue via click-to-conversion are preferred.
- If no sufficient revenue generating banners exist, then banners generating most clicks are chosen.
- If both are not found (e.g. in case of a newly created campaign), then any random banner associated with that campaign is chosen.
The application is also intelligent enough to avoid saturation.
- It sequence in which banners are served doesn't match to their revenue performance.
- It also serves different banners per campaign to each unique visitor and doesn't serve the same banner again until all chosen banners are served.
You need to have Docker Engine installed.
$ git clone https://github.com/ninadpdr/top-ad-banners.git$ docker build -t adbanners .
This will create a docker image on your system, ready to run the application.- Tests can be executed by command
$ docker run -it adbanners /bin/bash -c "rails db:test:prepare ; rails test" $ docker run -itP -p 3000:3000 adbannerswill start the application on port 3000 of your host.
It will take around 30 seconds to start as the database needs to be initialized with seed data every time.
Navigate to http://localhost:3000/campaigns/ to see all available campaigns.
- This is a Ruby-on-Rails application.
- Right now, it uses a sqlite3 database inside the same container as the application, which means the database needs to be created every time the container comes up. We can introduce additional dependency on Docker Compose, and easily fix this by adding another container running MySQL/Postgres, and using Docker Volumes to add persistent storage.
